If you think you can do it, you can.

I can, therefore I am.

The wise does at once what the fool does at last.

The secret of getting ahead is getting started.

Quality is not an act, it is a habit.

Be thine own palace, or the world's thy jail.

The dog that trots about finds a bone.

It's always too early to quit.

Without hard work, nothing grows but weeds.
